decrease) in salinity around the equator? Could it not be argued that higher temperature causes more evaporation from the ocean surface‚ which‚ in turn‚ results in higher salinity content? Figure 9.4 shows how the surface temperature of the ocean and the surface salinity change with latitudinal position. Salinity the measure of the concentration of dissolved salts in the ocean water. Salinity influences where plants and animals can thrive‚ and also affects aspects of water quality and treatment

Ocean OverfishingNicole HarrisENV/320June 23‚ 2014Frederick GrossOcean Overfishing Overfishing is a problem that occurs when fish are caught faster than they can reproduce. This is a problem that has been occurring for centuries and continues to be a problem today. Commercial fishing has driven many fish species to the brink of extinction. A scientific report done in 2003 estimates that industrial fishing “has reduced the number of large ocean fish to just 10-percent of their pre-industrial

Journey to the Ocean Floor Oceanography is a science that draws upon the methods and knowledge of geology‚ chemistry‚ physics‚ and biology to study the ocean. The Pacific Ocean is the largest and the deepest ocean. Most submersible dives follow a similar pattern‚ emphasizing bottom transecting‚ collecting and photographing specimens. To understand our ocean floor exploration‚ you must first know something about the ocean floor. Follow along below as I summarize the parts of the ocean floor.

The ocean has captivated mankind since the beginning of time. The Challenger Expedition‚ the first modern oceanography expedition‚ only began in 1872(“History of Oceanography”). Why was it that we ignored ocean research for so long? We have only “dipped our toes in the water” (Cousteau 194) and many people are afraid of taking a dive. However‚ ocean exploration is most certainly worth the risks‚ as the benefits of ocean research far outweigh the risks. Just two benefits of ocean research include

Coastal Erosion- The beach moving due to storms‚ waves‚ tide currents‚ drainage and high wind. Strength of the wave can be more powerful if the waves is longer and the wind is stronger can create erosive power. . Sea Level Rise- Shrink land ice‚ such as ice sheets‚ and mountain glaciers.

In the article‚ “Oceans Are Losing Oxygen—and Becoming More Hostile to Life” by Craig Welch‚ climate change is affecting the lives of all kinds of sea creatures. This article explains how climate change‚ and the warming of ocean water‚ has began taking oxygen out of the water. This means that many fish species have shrunk because of this loss of oxygen. The warmer water speeds up the metabolism of these fish‚ which makes them breathe in more of the oxygen. A couple of scientists from the University

Conclusion The chemical changes in ocean acidification is known to be caused by an increase in the concentration of carbon dioxide (CO2) in the atmosphere‚ resulting in the lowering of the pH making water more acidic‚ an increase in dissolved carbon dioxide (CO2)‚ a reduction in the concentration of carbonate ions and an increase in bicarbonate ions. The oceans are currently taking up about one ton of carbon dioxide (CO2) associated with human activities per year. Almost half of the carbon dioxide

Whales are the largest marine mammal in the world‚ living in all of the major oceans from the Arctic and Antarctic oceans to the tropical waters around the world. Human whaling is to hunt and kill whales for the use of their meat‚ oil and blubber. It is estimated that three million whales were killed in the twentieth century alone. According to the survey‚ there are only 10‚000 - 20‚000 whales surviving in the oceans today. Rapidly decreasing number of whales has affected the ocean’s ecosystem.

wonderful is it to stand on pearly sands watching the pure blue sky‚ so lonely without a cloud or a plane or even a bird fluttering across it and as you admire it‚ the sun’s ray’s beams down at you. But at the same time you hear the wave’s chants on the ocean. A visit to the beach is one of life’s greatest pleasures. I always‚ always look forward to summer‚ it is my favorite season and it’s the perfect time to have serious fun. What I love most about summer is its weather. It‘s always hot‚ which allows
